Thanks! Could you also provide a type test to this contribution? Look at this file as an example: https://github.com/bpmn-io/bpmn-js/blob/main/lib/BaseModeler.spec.ts

I didn't get the idea. I need to create an instance of ContextPadProvider and then what?

[barmac]

This code is not run, we just want to verify that the typescript compiler passes.

@barmac I decided to merge this one; as this is not about external API improvement, but internal typing I'm afraid there is not much we can simply test here.
